<h3>
    <a id="Explanation" name="Explanation">说明</a>
</h3>
<p>
    关联表示业务分析模型中业务工作者的实例和业务实体的实例之间的结构关系。它是必须保留一段时间的信息，并且不只是显示过程依赖关系。每个关联都有名称和多重性。多重性定义了可连接多少已连接的类的对象。它是显示可连接的对象数的一个常量或一个范围（例如，0..5
    ）。
</p>
<h5>
    示例：
</h5>
<p class="example">
    为乘客办理登机手续的代理人要遵循登记业务用例中描述其任务的一组指示信息。作为办理登机手续代理人的每个员工都应了解这些过程，以保证办理登机手续用例的平稳运作。业务工作者类“办理登机手续代理人”应与代表指令集的业务实体类有关联。
</p>
<h3>
    <a id="Roles" name="Roles">角色</a>
</h3>
<p>
    某些类型的关联可能有相当广泛的解释。对这些类型而言，在每个案例中指定特定的解释是非常重要的。出于这个目的，可指定所涉及的组织在关联中扮演的角色。若这不足以描述关联，那么也可以为关联命名。请避免使用“具有”和“包含”这样的名称，它们不会对关联已表示的含义再增加任何信息。
